Manpower of Lansing, Michigan, has informed authorities that a data breach stemming from a ransomware attack affects roughly 140,000 individuals.
The staffing and recruiting firm said in a data breach notice sent to impacted individuals that an investigation into an IT outage that caused disruptions on January 20, 2025, revealed that hackers had gained access to its systems.
The cybercriminals had access to Manpower’s network between December 29, 2024, and January 12, 2025. During that time they stole files containing personal information.
The Maine Attorney General has been informed that the details of 144,180 people were compromised as a result of the incident.
Impacted individuals are being offered free credit monitoring and identity theft protection services.
The RansomHub ransomware group listed Manpower on its leak site on January 22, claiming to have stolen 500 Gb of data and publishing various types of files to demonstrate its claims.
The hackers at the time claimed to have stolen HR, financial, marketing, and other corporate documents, along with databases and other files containing personal information.
There hasn’t been any activity on RansomHub’s website since April and its affiliates are believed to have been absorbed by the DragonForce group.
